• If you are trying to use Boolean operators, they must be ALL CAPS: %22jews %((2f education) OR (jrf education)) %((((2 germany) OR (12 germany))) OR (2 german)) %_ bavaria %((2f history) OR (imf history))%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22jews %((2f education) OR (jrf education)) %((((2 germany) or (12 germany))) or (2 german)) %_ bavaria %((2f history) or (imf history))%22".
• Adding a wildcard symbol may retrieve word variants: %22jews %((2f education) OR (jrf education)) %((((2 germany) or (12 germany))) or (2 german)) %_ bavaria %((2f history) or (imf history))%22*.
